LAN to LAN Bridge

I have a question about this LAN to LAN Bridge:
https://www.softether.org/4-docs/2-howt ... Bridge_VPN

Let's say my:
WAN1 LOCATION is: 1.1.1.1/30
WAN2 LOCATION is: 2.2.2.2/30

and my
LAN is 8.8.8.0/21

Can it be setup so that all IPs route out of WAN1 location? All the LAN Ip's are public in my situation (public ISP web servers). But only WAN1 actually has the 8.8.8.0/21 IP Range.

So if someone wants to get to a Server at 8.8.8.40 and it is at WAN2, it would rouite INTERNET -> WAN1 -> BRIDGE -> WAN2 -> 8.8.8.40
also server at 8.8.8.40 to get out would go to WAN2 -> BRIDGE ->WAN1 -> INTERNET

Note these are all fake IPs.

What do you mean " All the LAN Ip's are public in my situation (public ISP web servers)"

Are these machines behind a NAT firewall?

WAN2 location WAN Public address 2.2.2.2/30 ( fake IP address)==> NAT ===> Private address range 8.8.8.0/21 Local LAN network ( Web servers)?

My physical router (an EdgeRouter Pro) has a /30 as it's primary WAN and it's advertising a /21 that we own. There is no NAT.

So the LAN is basically all Public IP Addresses (we own a /21 block, 2048 public IPs) that are public web servers.

I want to tunnel those IPs to another location because of space and put them on same LAN.

Will this work?

This is beyond my area of expertise. Hopefully someone else has an answer?

I think it's possible.
What problem do you have?
